1.1.0 (2015-11-12)
- (Feature) OPAL now saves a vector to the workspace of those municipalities
(softboundary 3) that intersect the project footprint. This is only saved
when the softboundary 3 input is provided by the user.
- (Bugfix) Corrected an issue where testing future scenarios in the static map
generator would raise an exception.
- (Usability) Versioning replaced by `natcap.versioner`
- (Usability) OPAL UI is now offered in spanish as well as english.
- (Usability) OPAL UI allows for the user to select their language of choice among
those offered (currently english and spanish).
- (Feature) OPAL/MAFE-T report and output CSV values are rounded to 3 significant
- (Bufgix) Improved sorting by checkboxes in output report.
- (Usability) Improved logging to user within longer-running processes.
- (Feature) User's guide is tracked as a subrepository along with each build of
OPAL. User's guide version numbers are pulled from the OPAL source tree.
- (Feature) OPAL/MAFE-T report now includes the OPAL version used and a
time/date stamp.
- (Bugfix) The OPAL/MAFE-T report used to offer a hyperlink to the vector
(a multi-part ESRI Shapefile) containing the set of parcels matching
criteria. Clicking this link would only download part of the file.
It has been replaced with a text reference to the location of the file on
- (Usability) Select all/Select None buttons have been removed from the report.
They didn't work. They will be added back when they work properly.
- (Usability) Files within the workspace that are outside of the per-hydrozone
analysis are now hidden within an intermediate/ folder.
- (Usability) Various files have been renamed.
- (Bugfix) The headers of the top table of the output report now render in the
language of the OPAL run. They used to always render in english.
- (Bugfix) Parcels in the parcels table of the report are now correctly screened
to ensure that they are at least as large as the smallest impacted area
of the same ecosystem type.
- (Usability) The user is now unable to close the OPAL/MAFE-T execution dialog
unless the model run has completed or the process is terminated externally.
- (Bugfix) Better handling for when the user provides an ecosystem vector without
any features or when the vector is of the wrong type (points or lines instead
of polygons).
- (Usability) When a validated, optional input has its value removed from a UI
input, the green checkbox indicating input validity is now disabled.
- (Bugfix) OPAL UI now allows files containing any UTF-8 character to be selected
by the user.
- (Feature) Output vector of selected offsets now includes the distance from the
nearest impact site and the parcel size in the attribute table.
- (Bugfix) Output report had some columns that were incorrectly rounded to 1
decimal place instead of 2.
- (Usability) OPAL/MAFE-T will now confirm that the user wishes to overwrite the
workspace if files exist within the user-defined workspace. This dialog
is triggered if the user-defined workspace exists and there are files within.
- (Usability) OPAL/MAFE-T will now prompt the user for a language on startup
and remember the user's selection. The language may be set at any time
through File -> Select Language. Changing the language will trigger an
application restart.

1.0.3 (2015-3-20)
- (Usability) Improved many UI labels.
- (Usability) Improved folder name of the results folder.
- (Bugfix) Removed empty folders created by the tool in the workspace.
- (Bugfix) Corrected text of link to offsets vector in report.
- (Bugfix) Implemented automatic window sizing.
- (Usability) Filled in empty UI HelpText bubbles.
- (Usability) Renamed static map folder inputs to indicate it needs a folder.
- (Docs) Updated documentation to 1.0.3.
- (Bugfix) Clarified in report that impact/offset values are unitless unless
run on static maps generated by calibrated models.
- (Bugfix) Paths containing spaces now handled properly in UI.
- (Feature) If user does not define an AOI, the AOI column is not included in
the report.
- (Feature) Added Table of Contents to the output report.
- (Usability) Updated labels of Windows Start Menu shortcuts.
- (Bugfix) Offset parcels are now identified by a new column ("parcel_id") in
the selected_parcels.shp vector.
- (Bugfix) If there is only one subzone per zone, we omit the soft boundary 1
(subzone) column from the parcels table in the report.
- (Feature) Sped up initialization of the execution thread in the UI.
- (Feature) Updated CSS to improve readability of output report tables.
- (Feature) Added ability to export the parcels table to CSV.
- (Feature) Binary 1/0 values in report columns are now centered for readability.
- (Feature) UI now allows user to specify whether to open the workspace after
Successful execution. Once execution completes (regardless of success or
failure), the input changes to a button, allowing the user to open the
- (Feature) Parcels table in the report now includes a binary column indicating
whether each parcel is in the suggested set of parcels.
- (Feature) Updated InVEST version dependency to use more recent versions of
hydrological routing algorithms.
